YSJLThrottling Device
Throttling Device Flowmeter
Measures flow of liquids, gases, and steam by throttling differential pressure; nominal diameter 50–2600 mm, nominal pressure up to 42 MPa, accuracy ±1% to ±2.5% depending on calibration, with 4–20 mA DC output via differential pressure transmitter. Widely applied in petroleum, chemical, metallurgy, power, light industry, textile, and scientific research sectors for flow measurement, control, and regulation.
- Accuracy
- ±1%, ±1.5% (real flow calibration); ±2.5% (sampling calibration)
- Reynolds number range
- Standard type: 4×10³–1×10⁷; high viscosity type: 1×10³–1×10⁵ (calibrated)
- Output signal
- 4–20 mA DC (via differential pressure transmitter)
- Measuring principle
- Differential pressure throttling (Bernoulli equation)
- Suitable for petroleum, chemical, metallurgy, power, light industry, textile, scientific research, and military sectors
- Standard orifice plate with angle, flange, and D/D/2 pressure tapping options
- Annular orifice plate handles dirty fluids and reduces pressure tap blockages
- Integrated intelligent differential pressure transmitter enables temperature/pressure compensation
- Requires only 3DN upstream and 2DN downstream straight pipe sections for annular type
- Available with flange or welded connections

YSJL questions
What ranges are available for the YSJL?
Standard coverage is Standard type: 4×10³–1×10⁷; high viscosity type: 1×10³–1×10⁵ (calibrated). Other spans, outputs, and process connections can be sourced to match the application. Send the working pressure and medium and we will confirm the exact option.
What is the MOQ and lead time?
1 pc (flexible, no minimum for most products). 2-3 days for in-stock items, 15-30 days for custom orders. Samples are available, with freight on the buyer’s account.
Can the YSJL be customized?
Range, output signal, process connection, cable length customizable through our supply partners.
Do you manufacture this transmitter?
SIBXSUN is an industrial instrumentation supplier in Ningbo, not the factory. We source the YSJL from qualified partners, inspect before shipment, and handle export documents and logistics.
